What are the BAK and SFAPO files?

In my VEG-saving folder, there are also .BAK and .SFAPO files, bearing the same names as my VEG files.

I'm guessing the .BAK files are automatic backup saves that VEGAS performs from time-to-time as a courtesy. I'm also guessing that, being duplicates of your main VEG files, they can safely be deleted?

And what are the .SFAPO files? I notice that they cannot be deleted when the main VEG files are currently being loaded into VEGAS. So I suspect they hold some important information which SHOULDN'T be deleted?

The bak file can be renamed to .veg in case your current veg file becomes corrupt. And yes, it is the previous veg file that you saved before the last time you pressed the save button.

As for the other, when you wait for a file to build peaks, it creates that file so you no longer have to wait for it to rebuild the peaks. So if you delete it, Vegas will have to rebuild the peaks again.

Peaks are what you see when you look at the audio file. You see the wave form. Vegas builds the wave form and stores it in that file so that opening the project doesn't take a long time after the initial opening.

As for why it is not in the veg file itself... well, only Sony (and the original folks at Sonic Foundry) really know. My guess would be that it cuts down on clutter and file size.

Actually the .sfap0 file are not peaks. This is your audio from a nested project. You will only see these if you use nested projects that have audio. The peak files are .sfk files. The reason they are not saved in the .veg file is so they can be reused where ever that media is used.
